Title: Hair drier
IPC: A45D20/00
Filed: 1957-07-25
Abstract: 865,010. Hair driers. WEATHERHOLT, D. D., CHERRY, L. F., FULFORD, J. H., HOOEY, F. M., and WRIGHT, R. G. July 25, 1957 [July 25, 1956; June 6, 1957], No. 23620/57. Class 81 (2). [Also in Group XI] Apparatus for drying hair by a radio-frequency current comprises a generator for electromagnetic power of a frequency in the range 1- 150 megacycles and a conductor connected directly with the generator and disposed on the head so that the current produces an electric field in the region conforming to the disposition of the hair. The generator is connected by leads 139, 140 to a drying hood 300 which comprises an outer shell 321 and an inner insulating shell 320 between which two conducting rod frames 302 comprising branch rods 305-307 and 310-315, respectively, are arranged. An insulating lining 322 is provided between the rod frames and the outer shell. The rods of one rod frame alternate with the rods of the other rod frame, each rod frame being connected to a generator lead of opposite polarity, the electric field produced between the rods being concentrated in the region of the hair and negligible in the region of the head. At the top of the hood is an elongated hole 325. The generator comprises a direct-current power unit 103, connected to an oscillator 110, an amplifier 120, a power amplifier 130, a capacitatively coupled tank circuit 134 and a matching network 137 connected to the leads 139, 140. Closing of a master switch 153 causes energization of the direct current supply 103 and closes contacts 154 so that current flows through a resistor 155 and a normally closed relay contact 156. As the resistor 155 heats up, a bi-metallic strip closes a normally open contact 159 so that a relay 157 is energized to close contacts 159, 160 so that a second power unit 133 can be energized under the control of a timer 170. The second power unit supplies the anode voltage of the power amplifier 130. Closing of the master switch 153 also connects the timer 170 with the mains supply leads 101, 102. The timer includes a relay 200 which is normally energized through a valve 201 and a capacitor 202. On briefly pressing a button 203, a condenser 206 is charged through a selenium rectifier 204 and a resistor 205 and the valve 201 becomes non- conductive so that the timer relay 200 is deenergized and timer contacts 208, 209 are operated to prevent further charging of the condenser 206 and to permit energization of the second power unit 133. Radio-frequency energy is then supplied to the drying hood. When the condenser 206 has lost its charge through a resistor 210, the valve 201 again conducts and the timer relay 200 is re-energized to open contacts 208, 209 so that the second power unit 133 is deenergized and the hood ceases to operate. If drying of the hair is completed before the timer de-energizes the second power unit, a relay 180 is energized, owing to the drop in load of the second power unit as the hair dries, and normally closed contacts 181 open so that the power unit 133 is de-energized.

Title: Improvements in and relating to machines for making paper bags
IPC: B31B37/00
Filed: 1920-08-13
Abstract: 171,469. Welsford, L. W. Aug. 13, 1920. Paper bags, making. -Relates to a machine for making block-bottomed bags continuously from a web of paper and consists of the particular construction described. The machine is shown in side elevation in Fig. 1 and in plan in Fig. 2. A reel of paper 7, Fig. 1, is supported by an endless band 6 passing over rollers 4, and the webb 8 passes from the reel around a guide roller 9, which may have adjustable flanges, to a pasting-roll 12 which pastes it along one edge. After being gummed, the web is drawn around a templet 16 by grooved guiding - pulleys 17<a> which extend over the edges of the templet and thus form the web into a tube. In front of the templet are two drawing-rolls 21, 22 which draw the paper tube forwards and feed it between creasing and cutting rolls 23, 24. These rolls carry serrated cutting knives, which cut from the tube a length suitable for making a bag, and also ridges and depressions which cooperate to crease the blank along the line 27, Fig. 7, and along the diagonal lines 30. A spring tongue rod or forked member 35 attached to the templet 16 extends through central recesses or grooves in the rollers 22, 24 and is therefore surrounded by the paper tube and blank. The forks are provided with upstanding teeth situated just in front of the roller 23. These teeth raise the front edge of the blank so that it is engaged by a hook 38, Fig. 6, pro. jecting downward in front of the roll 23, and is folded back to form the diamond fold, as shown in Fig. 7. The fold is completed by a guiding tongue 40, and the blank next passes between rolls 41, 42, the upper roll 41 being provided with gumming-pads which receive gum from a box 46 and gum the bottom folds. Hooks 51, 56 successively fold the bag bottom on the creases 48, 48<a>, Fig. 8, thus completely folding over the bottom as shown in Fig. 9, the gummed parts being secured by passing between pressing rolls 58, 59. The bottom is finally folded back again along the crease 48<a> by means of a knotted cord 63, Fig. 1, which travels above the bag at a higher speed. A knot on the cord engages. the bag bottom and opens it out about the crease 48a. The lower rolls of each pair are mounted in ball-and-cup bearings, and the upper rollers are kept in contact with the lower by means of adjustable springs.

Title: Improvements in and relating to driving devices for aircraft fuel pumps connected in parallel to a common delivery conduit
IPC: B64D37/02
Filed: 1956-08-02
Abstract: 803,836. Centrifugal pumps. SVENSKA AEROPLAN A. B. Aug. 2, 1956 [Aug. 6, 1955], No. 23824/56. Class 110 (1). [Also in Group XXIX] Aircraft fuel pumps 9a, 9b, 9c, 9d, Fig. 1, connected in parallel to a common delivery line 10, are driven by separate hydraulic motors 6a, 6b, 6c, 6d which are supplied with motive fluid by an engine-driven variable-delivery hydraulic pump 1, and a valve mechanism 5 connects the motors successively to the pump 1 in such a way that as soon as one motor has reached the optimum speed range of its fuel pump, a further motor is put into operation, and conversely the motors are successively disconnected as the speeds fall below the optimum range. The motors exhaust to a common line 8 which returns the fluid by way of a reservoir 2 to the inlet of the pump 1. The valve mechanism 5 comprises an inlet 13, Fig. 2, from the pump 1 and outlets 12a, 12b, 12c, 12d to the motors 6a, 6b, 6c, 6d respectively. Fluid flows to the motor 6a through a metering nozzle 19a in a spring-loaded valve 17a. When the flow reaches a value corresponding to the optimum speed range of the motor 6a, it moves the valve 17a to uncover a passage 14a admitting fluid by way of a valve 17b to the motor 6b. As the flow from the pump 1 further increases, passages 14b and 14c are successively opened to admit fluid to the motors 6c and 6d respectively. If the flow increases sufficiently, valve 17d is moved to uncover a relief passage 14. With decreasing flow the motors are disconnected in the reverse order. Instead of being responsive to flow or dynamic pressure, the valve mechanism may be made directly responsive to the speed of the motors. In this case, the valves are actuated by centrifugal governors on the shafts of the motors. Instead of stopping when the valves are closed, the motors may be run at an idling speed by means of fluid leaking past the valves or admitted through separate passages. The pumps may be provided with non-return valves.
